This paper presents a defect analysis and performance evaluation of photovoltaic (PV) modules using quantitative electroluminescence imaging (EL). The study analyzed three common PV technologies: thin-film, monocrystalline silicon, and polycrystalline silicon.
Although thermomechanical damage incurred during PV module production may not immediately impact output, the cumulative effects of cracking can become significant over time, especially as PV modules are exposed to thermal cycling (TC) and environmental loads in the field.
The long-term performance of photovoltaic (PV) modules declines over time, influenced by environmental conditions such as temperature, humidity, and shading, which pose operational challenges. Quantifying this long-term degradation is crucial for predicting the return on investment of PV systems.
For polycrystalline PV panels, performance degradation is often influenced by factors such as hotspots, micro-cracks, potential-induced degradation, delamination, and the presence of dark cells. The measurement results using EL technology on two PV panels after 12 years of operation are presented in Table 6. Table 6.
